Here is a satirical book by Joey Vimsante.
It is a comedy satire of a land where everyone is rude to each other, but one person decides to campaign against that.
The short story is called First World Problems.
It can be found on amazon at;

A world where people are deeply offensive to eachother. One person decides to campaign against that, in the face of saying the insults are first world problems.
What does everyone think?

It's hard to offer critique of this very short book without a sample of the writing. Insults are a third world problem too. Read Behind the Beautiful Forevers, a true story of Indian slum life: https://en.wikipedia.org/wiki/Behind_the_Beautiful_Forevers

Funny idea but yeah, it's hard to comment without the actual text.
